Chemical Structure

β-entiobiose octaacetate CAS 4613-78-9 chemical structure

Description

The occurrence of β-entiobiose octaacetate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies β-entiobiose octaacetate (CAS 4613-78-9), a certified reference material (molecular formula C28H38O19, MW 678.59 g/mol) for analytical method development and quality control.

Based on its molecular formula C28H38O19, β-entiobiose octaacetate contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 678.59 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), β-entiobiose octaacetate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
